Description

Technical Field

[0001] The invention relates to the technical field of animal fat refining, in particular to an animal fat refining device and a refining method. Background Art

[0002] In the field of food processing and oil extraction, animal fat refining is a long-standing and crucial process. Animal fat, as a natural resource rich in saturated and unsaturated fatty acids, can be widely used in cooking, baking, pharmaceuticals, biofuels and other industries after refining. The refining process not only improves the quality and stability of the fat, but also ensures the safety and hygiene standards of the product. The basic process of animal oil refining usually covers several key stages, including raw material cutting, pressing or leaching extraction, refining (including deacidification, decolorization, deodorization and other steps) and finished product storage. Among them, raw material cutting is the basis of the entire refining process, which directly affects the efficiency of subsequent steps and the quality of the final product. It is required to cut the raw materials into fine particles with uniform particle size in order to increase the contact area during oil extraction, promote the effective release of oil, and facilitate subsequent transportation and processing; However, the existing technology faces a significant technical challenge after the animal fat raw material cutting stage: the lack of an effective particle size monitoring mechanism. The uniformity of particle size is crucial to the oil refining process, because inconsistent particle sizes may lead to uneven oil extraction, and some raw materials fail to fully release oil, thereby reducing the overall oil yield. In addition, the difference in particle size may also affect the removal efficiency of impurities during the refining process, resulting in the finished oil containing more impurities, affecting its color, flavor and stability. Another urgent problem to be solved is that animal oil raw materials are rich in natural oils and their surfaces are often covered with a layer of oil film. After cutting, this layer of oil film makes it easy for the raw material particles to adhere to each other. Especially during the transportation process, due to friction and extrusion, the adhesion phenomenon is more significant. The adhesion of raw materials will not only increase the difficulty of transportation, cause equipment blockage and increase energy consumption, but more importantly, it will interfere with the continuity of subsequent refining processes, making it impossible for some raw materials to be evenly dispersed in the refining medium, thereby affecting the separation and purification of oils. In the long run, this adhesion phenomenon may also cause a large amount of oil residue to accumulate inside the equipment, increasing the difficulty of cleaning and maintenance, and is also not conducive to food safety and hygiene.

[0021] An animal fat refining device and a refining method, specifically comprising the following steps: Step 1. Fill a proper amount of water into the water tank and start the first motor. The output end of the first motor rotates through the first connecting rod to drive the driving block to rotate. The driving block rotates to push the third filter plate to move upward, squeezing the second filter plate to move downward. The upward movement of the third filter plate will stretch the second spring to elastically deform, and prompt the second telescopic rod to move upward along the inner cavity of the second support tube. The downward movement of the second filter plate will squeeze the first spring to elastically deform, and prompt the first telescopic rod to move downward along the inner cavity of the first support tube. With the rotation of the driving block, when the second filter plate and the third filter plate are separated from the driving block, the third filter plate will be pulled to return to its initial position under the elastic action of the second spring, and the second filter plate will be pushed to return to its initial position under the elastic action of the first spring, and the above process is repeated. The above-mentioned action will cause the second filter plate and the third filter plate to vibrate, start the high-pressure water pump, the high-pressure water pump pumps out water through the water inlet pipe, and delivers water to the high-pressure nozzle through the drain pipe, the water distributor and the delivery pipe, and the water is sprayed to the top of the third filter plate through the high-pressure nozzle at high pressure, and the second motor is started. The output end of the second motor is used to drive the driving frame to rotate through the second connecting rod, so that the driving frame drives the sliding column to rotate with the second connecting rod as the center of the circle. The sliding column rotates with the second connecting rod as the center of the circle and cooperates with the driving plate to drive the rack on the left side to reciprocate left and right. The left and right reciprocating motion of the rack on the left side cooperates with the first gear to cause the rack on the right side to reciprocate left and right, and then the reciprocating rack is used to drive the stirring telescopic rod to reciprocate left and right through the sleeve rod; Step 2: The animal fat raw materials that have been cut are transported to the top of the third filter plate. As the third filter plate vibrates, the animal fat raw materials on the surface of the third filter plate will move forward. When the animal fat raw materials move to the support frame, the high-pressure water sprayed from the high-pressure nozzle will be used to perform high-pressure washing on the animal fat raw materials. Not only the animal fat raw materials are washed, but also the strong water flow impact force generated by the high-pressure nozzle is directly applied to the surface of the animal fat raw materials. At the same time, the permeability of water is used to further destroy the adhesion of the fat, thereby promoting the separation of the animal fat raw materials. The animal fat raw materials are stirred and fiddled with by a stirring telescopic rod that moves back and forth left and right, thereby further destroying the adhesion structure of the fat and making the animal fat raw materials easier to separate. The separated animal fat raw materials will be filtered by the vibrating third filter plate, and the particle size is uneven. Animal oil with larger particle size The fat raw materials will remain on the surface of the third filter plate, and move to the front side of the third filter plate, fall off the surface of the third filter plate, and be collected and processed uniformly. The remaining animal fat raw materials will fall onto the surface of the second filter plate, and the second filter plate will be used to further filter the animal fat raw materials on its surface. The animal fat raw materials with uneven particle sizes and smaller particle sizes will pass through the filter holes of the second filter plate and fall onto the surface of the first filter plate, and move to the front side of the first filter plate, fall off the surface of the first filter plate, and be collected and processed uniformly. The animal fat raw materials remaining on the surface of the second filter plate are qualified animal fat raw materials with uniform particle sizes, and will move to the front side of the second filter plate, fall off the surface of the second filter plate, and fall into the inner cavity of the filter cartridge. At the same time, the water sprayed from the high-pressure nozzle will pass through the filter holes of the third filter plate, the second filter plate and the first filter plate and fall into the inner cavity of the support seat, and flow back to the inner cavity of the water tank through the water tank. The third motor is started, and the output end of the third motor rotates to drive the second gear to rotate through the third connecting rod. The second gear rotates and cooperates with the gear ring on the front side to cause the filter cartridge to rotate. The rotation of the filter cartridge causes the animal fat raw material in its inner cavity to tumble and move forward with the inner wall of the filter cartridge. While the filter cartridge rotates, the gear ring on the rear side and the third gear cooperate to cause the second rotating rod to rotate. The rotational force generated by the rotation of the second rotating rod causes the rubber belt to whip the filter cartridge, thereby causing the filter cartridge to vibrate to prevent the animal fat raw material from adhering to the inner wall of the filter cartridge. The hot air sprayed from the nozzle is used to dry the animal fat raw material in the inner cavity of the filter cartridge to remove the residual moisture on its surface. The dried animal fat raw material moves out of the inner cavity of the filter cartridge through the front side of the filter cartridge and falls into the oil boiling pot for animal fat refining.

[0022] This device effectively solves the problems of uneven particle size and easy adhesion of raw materials after cutting, thereby ensuring the efficiency and stability of subsequent refining steps. This device not only improves the overall oil yield and product quality, but also significantly reduces production costs and equipment maintenance difficulties, providing strong support for the sustainable development of the animal fat refining industry.

The driving block (20) rotates to push the third filter plate (16) to move upward, and squeezes the second filter plate (13) to move downward. The upward movement of the third filter plate (16) stretches the second spring (17) to undergo elastic deformation, and prompts the second telescopic rod (15) to move upward along the inner cavity of the second support tube (9). The downward movement of the second filter plate (13) squeezes the second filter plate (13). The first spring (14) is compressed to cause elastic deformation and the first telescopic rod (12) is urged to move downward along the inner cavity of the first support cylinder (10). As the driving block (20) rotates, when the second filter plate (13) and the third filter plate (16) are separated from the driving block (20), the third filter plate (16) is pulled back to its initial position under the elastic action of the second spring (17).

As the third filter plate (16) vibrates, the animal fat raw material on the surface of the third filter plate (16) moves forward. When the animal fat raw material moves to the support frame (71), the high-pressure water sprayed by the high-pressure nozzle (719) is used to high-pressure wash the animal fat raw material. Not only is the animal fat raw material washed, but the strong water flow impact force generated by the high-pressure nozzle (719) is also used to directly act on the surface of the animal fat raw material. At the same time, the permeability of water is used to further destroy the adhesion of the fat, thereby promoting the separation of the animal fat raw material. The animal fat raw material is stirred and poked by the stirring telescopic rod (717) that moves back and forth left and right, further destroying the adhesion structure of the fat, making the animal fat raw material easier to separate. The separated animal fat raw material is filtered by the vibrating third filter plate (16). The particle size is uneven.

The hot air blown by the hot air blower (810) is blown into the inner cavity of the nozzle (814) through the hot air pipe (811), the connecting pipe (812) and the air pipe (813). The hot air is ejected through the nozzle (814) and sprayed toward the filter cartridge (82). The third motor (84) is started. The output end of the third motor (84) rotates to drive the second gear (86) to rotate through the third connecting rod (85). The rotation of the second gear (86) cooperates with the gear ring (83) located on the front side to cause the filter cartridge (82) to rotate.
